Ten kinds of materials of soil and mineral were used in this experiment Materials were set up in a bag with carbon dioxide from dry ice, and then closed it for 1, 3, and 5 days. The quantitative carbon contents in the materials were analyzed by NCS elemental analyzer, before and af­ter the experiments. The result shows that the leaf mold and slaked lime were fitted for the fixation of carbon dioxide 9.1 wt%, and 8. 7 wt%, respectively. The fixation of carbon dioxide did not depend on the water content, pH, and grain size of these materials. FT-IR analysis indicated that the chemical bonds have changed after treatments. In the case of slaked lime, transmittance of OH group decrease after calcite forma­tion [Ca(OH)2+C02→ CaCO3+H2O]. In the case of leaf mold, carbon would com­bine with sulfur or methyl group, and that methyl group would also combine with phosphorus.}, pages = {15--22}, title = {土壌による二酸化炭素の固定と浄化の可能性}, volume = {23}, year = {2000} }
